RESUMEN

OBJECTIVE: Bronchogenic carcinoma (BC) is the second most frequent worldwide and the most lethal tumour in both sexes. Its incidence varies not only among countries but also among different areas of the same country. So, the aim of this work was to analyse the evolution of its incidence and survival in the province of Castellón from 2004 to 2017 and to compare them with those of de rest of the country. METHODS: A retrospective observational study was carried out from patients diagnosed with BC and registered in the Castellón Tumour Register from 2004 to 2017. Survival was estimated using the Kaplan-Meier method whereas to estimate the relationship among different variables both the chi-square and ANOVA test were used. RESULTS: 4,346 cases were diagnosed, whose mean age was 67.5±11.3 years, 85.2% men, the most frequent histological types were adenocarcinoma (28.3%) and epidermoid carcinoma (25.1%). The gross global incidence was 53.4 cases/105 inhabitants, 90.9 cases/105 men and 15.7 cases/105 women. Median global survival at five years was 12.7%, 12% in men and 18.4% in women. CONCLUSIONS: The global incidence of BC in Castellón is lower than the national one, having remained stable in men while it is double in women. Global survival at five years is less than 15%, being higher in women than in men, nevertheless it increases compared to that of previous studies.


OBJETIVO: El carcinoma broncogénico (CB) es el segundo tumor más frecuente a nivel mundial y el más letal en ambos sexos. Su incidencia varía, no sólo entre países, sino también entre diferentes zonas de un mismo país. Por tanto, el objetivo de este trabajo fue analizar la evolución de su incidencia y la supervivencia en la provincia de Castellón desde 2004 hasta 2017, y compararlas con las del resto del país. METODOS: Se realizó un estudio observacional retrospectivo en pacientes diagnosticados de CB e inscritos en el Registro de Tumores de Castellón desde 2004 hasta 2017. La supervivencia se estimó mediante el método de Kaplan-Meier, mientras que para estimar la relación entre distintas variables se utilizaron los test Chi-cuadrado y ANOVA. RESULTADOS: Se diagnosticaron 4.346 casos, con una edad media de 67,5±11,3 años, el 85,2% eran hombres, los tipos histológicos más frecuentes fueron adenocarcinoma (28,3%) y carcinoma epidermoide (25,1%). La incidencia global bruta fue de 53,4 casos/105 habitantes, con 90,9 casos/105 de hombres y 15,7 casos/105 de mujeres. La mediana de supervivencia global a los cinco años fue del 12,7%, siendo del 12% en hombres y del 18,4% en mujeres. CONCLUSIONES: La incidencia global de CB en Castellón es inferior a la nacional, habiéndose mantenido estable en hombres mientras que se duplica en mujeres. La supervivencia global a los cinco años es inferior al 15%, siendo mayor en mujeres que en hombres; no obstante, aumenta respecto a la reportada en estudios previos.

RESUMEN

INTRODUCTION: Bronchogenic carcinoma accounts for more cancer-related deaths than any other malignancy and is the most frequently diagnosed cancer in the world. Bronchogenic carcinoma is by far the leading cause of cancer death among both men and women, making up almost 25% of all cancer deaths. The objective of this study was to identify the changing trends, if any, in radiological patterns of bronchogenic carcinoma to document the various computed tomography (CT) appearances of bronchogenic carcinoma with histopathologic correlation. METHODS: This was a single-center cross-sectional study on 162 patients with clinical or radiological suspicion of bronchogenic carcinoma with histopathological confirmation of diagnosis. RESULTS: There was a male preponderance with bronchogenic carcinoma and smoking being the most common risk factor. Squamous cell carcinoma followed by adenocarcinoma and small cell carcinoma is the most common histologic subtype. Squamous cell carcinoma was noted to be present predominantly in the peripheral location (55.5%), and adenocarcinoma was noted to be present predominantly in the central location (68.4%). CONCLUSION: CT is the imaging modality of choice for evaluating bronchogenic carcinoma and provides for precise characterization of the size, extent, and staging of the carcinoma. Among 162 bronchogenic carcinoma cases evaluated in the current study, a definite changing trend in the radiological pattern of squamous cell carcinoma and adenocarcinoma was observed. Squamous cell carcinoma was predominantly noted to be a peripheral tumor, and adenocarcinoma is predominantly noted to be a central tumor. Surveillance or restaging scans are recommended, considering the high mortality rate in patients with bronchogenic carcinoma.

RESUMEN

Clasificar los carcinomas de pulmón según criterios establecidos por la OMS 2015 en biopsias de la sección de patología respiratoria del Instituto Anatomopatológico "Dr. José Antonio O`Daly" en el período enero 2006-diciembre 2016. Se realizó estudio descriptivo y retrospectivo, en el que se evaluaron todos los casos de carcinomas pulmonares recibidos entre enero 2006 diciembre 2016. La edad de presentación del carcinoma pulmonar fue 61 ± 11,45 años. Fue más frecuente en el sexo masculino 56,57 %. El tipo histológico más frecuente fue el adenocarcinoma 61,6 %. El adenocarcinoma el patrón predominantemente sólido fue el más constante 57,3 %, seguido de patrón predominantemente acinar 18,2 % y patrones mixtos. El carcinoma de células escamosas fue el segundo tipo más frecuente con 30,3 % de los casos representando el carcinoma de células escamosas poco diferenciado no queratinizante un 40 %. El carcinoma neuroendocrino fue el tercer tipo de carcinoma más común y el carcinoma de células pequeñas representó el 80 % de estos casos. Al menos 10,8 % de los casos fueron carcinomas no clasificables por necrosis o muestra escasa. Los casos previamente diagnosticados como adenocarcinoma poco diferenciado se corresponden con patrón sólido. Es importante el uso de inmunohistoquímica para el diagnóstico definitivo especialmente de adenocarcinoma patrón predominantemente sólido. El uso de la actual clasificación permite definir pronóstico y tratamiento personalizado(AU)


To classify the lung carcinomas according to criteria established by WHO 2015 in the biopsies of the section of respiratory pathology of the Anatomo Pathological Institute "Dr. José Antonio O`Daly" in the period January 2006 December 2016. A study will be carried out descriptive and retrospective, in which all cases of the pulmonary carcinomas received between January 2006 and December 2016 were evaluated. The age of presentation of the lung carcinoma was 61 ± 11.45 years old. It was more frequent in the male sex 56.57 %. The most frequent histological type was the adenocarcinoma 61.6 %. The predominantly solid adenocarcinoma pattern was the most constant 57.3 % followed by predominantly acinar pattern 18.2 % and the mixed patterns. The squamous cell carcinoma was the second most frequent type 30.3 %, and the poorly differentiated and non-keratinizing type was a 40 %. The neuroendocrine carcinoma was the third most common type of it the small cell carcinoma accounted an 80 %. At least 10.8 % of the cases were carcinomas unclassifiable due to necrosis or scarce sample. The cases previously diagnosed as poorly differentiated adenocarcinoma correspond to a solid pattern. The immunohistochemically use is important for the definitive diagnosis, especially for the adenocarcinoma predominantly solid pattern. The use of the current classification allowsdefining the prognosis and the personalized treatment(AU)

RESUMEN

BACKGROUND: Metastatic disease to the eye most commonly involves choroid followed by orbit leading to varied ocular manifestations. By comparison, it is relatively rarer than primary malignancies of eye as well as metastasis in other parts of the body. AIM: The aim of this study is to evaluate the common eye and orbital structures involved in secondary ocular and metastatic disease, to describe its clinical manifestations and outline the management done. METHODS: A retrospective study of newly diagnosed cases of ocular metastasis in last 2 years conducted in our recently established department of ocular oncology at a tertiary eye care hospital in Nepal. Demography, age and sex distribution were noted. The patients were segregated into those with secondary or metastatic ocular malignancies. Detail study on the metastatic disease to eye was made in regards to presenting symptoms, signs, primary site of cancer, and the treatment done. Details of the investigations done, like biopsy and imaging were also recorded. RESULTS: There were a total of 28 patients, whose age group ranged from 9 years to 69 years with median age of 43 years. Females constituted 46% of total patients. Both the eyes were involved in 9 patients (32%). Eye was secondarily involved by paranasal sinus tumors and Non Hodgkin lymphoma (7 patients each). Ocular metastasis was commonly seen from broncogenic carcinoma in four and breast carcinoma in three patients. Simultaneous metastasis to other parts of the body was also seen in 61% of our patients. Diminution of vision in 49% was the most common presenting feature followed by proptosis in 16% and palpable mass in 14% of patients. Orbit in 43% cases is the commonest ocular structure involved. Histopathologic diagnosis was done in 32% only while rest was based on imaging alone. The most common treatment done was chemotherapy in 57% patients. CONCLUSION: Ocular metastasis can display a wide variety of clinical and imaging features and therefore a high degree of suspicion is required. It is often associated with simultaneous metastasis to other parts of the body as well, hence the importance of earlier diagnosis and metastatic workup.

RESUMEN

BACKGROUND: Cancer and pulmonary tuberculosis are major global health concerns and are associated with substantial morbidity and mortality. The association between active tuberculosis and subsequent cancer development has been investigated for many years. This study was planned to determine the prevalence of latent tuberculosis infection in patients with recently diagnosed bronchogenic carcinoma. METHODS: Sixty-four newly diagnosed primary lung cancer patients were enrolled. Diagnosis of latent tuberculosis infection was performed with QuantiFERON-TB Gold In-Tube tests, with exclusion of active tuberculosis. RESULTS: Latent tuberculosis infection was detected in 16 (25%) patients, and 8 (12.5%) had indeterminate results of the QuantiFERON-TB Gold In-Tube test. Being a current smoker was associated with a higher prevalence of latent tuberculosis (p = 0.001). Comorbidities, tumor site, and histopathology were not associated with latent tuberculosis infection. CONCLUSIONS: There is a considerable risk of concurrent latent tuberculosis in newly diagnosed primary bronchogenic carcinoma. The need for treatment of latent tuberculosis in these patients and its influence on the outcome and prognosis are issues for further investigations.

RESUMEN

INTRODUCTION: Skeletal-related events (SRE) are common in patients with bone metastatic lung cancer and have a negative impact on quality of life and survival. The objective of this study is to identify predictive factors for SRE occurrence among this population. METHODS: We conducted a 3-year retrospective study including 100 lung cancer patients with bone metastasis. RESULTS: Eighty-two patients presented at least one SRE (69.5% at baseline). The median occurrence for SRE was 4.5 months and severe bone pain was the most common SRE (56%). The alkaline phosphatase serum level>120IU/L (hazard ratio [sHR]=2.8; 95% confidence interval (CI) [1.5-5.4]; P=0.002) and calcemia>2.6mmol/L ([sHR]=9.7; 95% CI [5.1-18.4]; P<0.001) were identified as risk factors for SRE occurrence while the presence of an initial SRE was associated with a decrease of this risk ([sHR]=0.2; 95% CI [0.1-0.4]; P<0.001). CONCLUSION: The elevated alkaline phosphatase serum level and hypercalcemia are risk factors for SRE occurrence in bone metastatic lung cancer patients and should be used as biomarkers to adapt current medical practice for these patients.

RESUMEN

Lung cancer remains the most lethal cancer. The most common cause is smoking, which is also preventable, unlike the causes of other types of cancer. A genetic characteristic has emerged over several years, which explains particular profiles of smokers, or highly dependent smokers. The emergence of new therapies for the treatment of lung cancer, and the impact of tobacco on reducing the effectiveness of these therapies must challenge practitioners to obtain a complete cessation of smoking regardless of the stage of the disease.

RESUMEN

INTRODUCTION: In the context of underreporting of occupational diseases, the aim was to study the validity of silica and asbestos job-exposure matrices in screening occupational exposure in the field of thoracic oncology. METHODS: Fifty patients hospitalized with primitive lung cancer or mesothelioma in a university hospital center in the Hauts-de-Seine department of France were included between November 2016 and September 2017. For each patient 1/the job history was collected, from which data was entered single-blindly into the job-exposure matrices by a resident in occupational medicine, 2/a questionnaire (Q-SPLF) was completed similarly, and 3/the patients also had a consultation with a chief resident in occupational medicine, considered the gold standard. The main outcome was the diagnostic performance of the matrices. The Q-SPLF diagnostic performance was also studied. RESULTS: The asbestos and silica matrices had sensitivities of 100%, specificities of respectively 76.1% and 87.8%, the positive likelihood ratios were at 4.19 [2.5-6] and 8.17 [3.8-10], and the negative likelihood ratios were at 0. The Q-SPLF diagnostic performance was comparable to that of the matrices. CONCLUSIONS: The matrices and the questionnaire have a great diagnostic performance which seems interesting for a use as a screening tool for occupational exposures. These results have yet to be confirmed by large-scale studies.

RESUMEN

Soluble Triggering Receptor Expressed on Myeloid Cells 1 (sTREM-1) can be found in the sera of patients with infectious, autoimmune and malignant diseases. The primary objective of this study was to investigate the prognostic significance of sTREM-1 in lung cancer patients. We analyzed the sera of 164 patients with lung cancer of all histologies and all stages at the time of diagnosis. We employed an ELISA using the anti-TREM-1 clone 6B1.1G12 mAb and recombinant human TREM-1. Patient data was collected retrospectively by chart review. In ROC-analysis, a sTREM-1 serum level of 163.1 pg/ml showed the highest Youden-Index. At this cut-off value sTREM-1 was a marker of short survival in patients with NSCLC (median survival 8.5 vs. 13.3 months, p = 0.04). A Cox regression model showed stage (p < 0.001) and sTREM-1 (p = 0.011) to indicate short survival. There were no differences in sTREM-1 serum values among patients with or without infection, pleural effusion or COPD. sTREM-1 was not associated with metastasis at the time of diagnosis and was not a predictor of subsequent metastasis. In SCLC patients sTREM-1 levels were lower than in NSCLC patients (p = 0.001) and did not predict survival. sTREM-1 did not correlate with CRP or the number of neutrophils. In non-small cell lung cancer patients, sTREM-1 in serum has prognostic significance.

RESUMEN

Introducción y objetivos: Algunas características del cáncer de pulmón han cambiado en las décadas recientes. El objetivo es conocer las características del cáncer de pulmón diagnosticado en nuestro centro. Métodos: Se analizan los casos diagnosticados entre 18/02/2008 y 18/02/2013. Se excluyen los no confirmados citohistológicamente. Resultados: En el periodo referido se diagnosticaron 307 casos, 244 (79,5%) varones y 63 (20,5%) mujeres, con una edad media de 65,37 años (DE ± 11,27). La edad media de los varones fue 66,73 ± 10,53 años y 60,14 ± 12,6 la de las mujeres (p= 0,0001). El 97% de los varones fumaba o había fumado, frente al 63% de las mujeres. La forma de presentación más frecuente fue la alteración radiológica en un paciente asintomático. El adenocarcinoma fue la estirpe tumoral más frecuente en varones y mujeres, con 117 (38,1%) casos en total, seguido del carcinoma epidermoide con 77 (25,1%) casos, y del carcinoma de célula pequeña con 58 (18,9%). Más del 65% de los pacientes con carcinoma de célula no pequeña presentaban al diagnóstico una enfermedad localmente avanzada (22,5%) o diseminada (43%). El porcentaje de enfermedad avanzada fue superior en el adenocarcinoma (71%) comparando con el carcinoma epidermoide (51%, p= 0,004). Conclusiones: El cáncer de pulmón diagnosticado en nuestro centro se caracteriza por una edad media cercana a los 65 años, un porcentaje alto de mujeres, una edad media significativamente menor en el grupo de mujeres, predominio del adenocarcinoma tanto en varones como en mujeres y un porcentaje significativamente mayor de pacientes con enfermedad avanzada entre los adenocarcinomas en comparación con los carcinomas epidermoides


Introduction and objectives: Some features of lung cancer have changed in recent decades. The objective is to find out the features of lung cancer diagnosed at our center. Methods: Cases diagnosed between 02/18/2008 y 02/18/2013 are analysed. Cases not citohistologically confirmed are excluded. Results: 307 cases were diagnosed during the study period, 244 (79.5%) men and 63 (20.5%) women, with a mean age of 65.37 years (DE ± 11.27). Mean age was 66,73 ± 10,53 years among men and 60.14 ± 12.6 among women (p= 0.0001). Among men 97% were smokers or former smokers, versus 63% of women. The most frequent way of presentation was a radiological finding in an asymptomatic patient. Adenocarcinoma was the most frequent histology among men and women, with a total of 117 (38.1%) cases, followed by squamous cell carcinoma with 77 (25.1%) cases and small cell carcinoma with 58 (18.9%). More than 65% of patients with non-small cell carcinoma presented at diagnosis with a locally advanced (22,5%) or disseminated disease (43%). The percentage of patients with advanced disease was higher among adenocarcinoma (71%) compared to squamous cell carcinoma (51%, p= 0.004). Conclusions: Lung cancer diagnosed at our center is characterized by a mean age near 65 years, a high percentage of women, a higher mean age in the group of women, adenocarcinoma as the most frequent histology among men and women and a higher percentage of patients with advanced disease among adenocarcinomas in comparison to squamous cell carcinomas

RESUMEN

OBJECTIVES/HYPOTHESIS: Branchial cleft cysts rank among the most common differential diagnoses of cystic cervical masses. Rarely, classic cystic structures exhibit a squamous cell carcinoma differentiation that represents a bronchogenic carcinoma. The existence of bronchogenic carcinoma is controversial due to the lack of systematic immunohistologic workup. The present study aimed to identify the clinical and immunohistologic features of bronchogenic carcinoma to clearly distinguish this entity from other cystic cervical masses. METHODS: Immunohistologic (epidermal growth factor receptor; cytokeratin 5, 6, 7, 13; and p16) and epidemiologic assessments were performed for branchial cleft cysts (n = 63), bronchogenic carcinomas (n = 5), cystic metastasized oropharyngeal carcinomas (n = 97), and carcinomas of unknown primary (n = 51). The study was conducted as a retrospective case series study with comparison. RESULTS: The patients with bronchogenic carcinomas differed significantly in age and in the number of involved lymph nodes compared with the cystic metastasized oropharyngeal carcinoma (and carcinoma of unknown primary) patients. Regular histologic wall structures were only observed in the bronchogenic carcinomas and branchial cleft cysts. Solitary cytokeratin-7 staining was only observed in the bronchogenic carcinomas, and all of the bronchogenic carcinomas were p16 negative. CONCLUSIONS: The existence of bronchogenic carcinoma seems to be plausible based on clinical findings. Cytokeratin-7 and p16 staining might be helpful in the diagnostic workflow. LEVEL OF EVIDENCE: 4 Laryngoscope, 126:638-642, 2016.

RESUMEN

BACKGROUND: Lung transplant is the only available therapy for patients with advanced lung disease. The goal of this study was to examine the prevalence, origin, management and outcome of lung cancer in recipients of lung transplant at our institution. METHODS: After institutional review board approval, we conducted a retrospective chart review of all lung transplantations in our institution from January 1990 until June 2012. RESULTS: The prevalence of lung cancer in the explanted lung was 6 (1.2%) of 462 and all cases were in subjects with lung fibrosis. All 4 subjects with lymph node involvement died of causes related to the malignancy. Nine (1.9%) of 462 patients were found to have bronchogenic carcinoma after lung transplant. The most common location was in the native lung in recipients of a single lung transplant (6 out of 9 patients). In one case, the tumor originated in the allograft and was potentially donor related. The median time to diagnosis after lung transplant was 28 months with a range from 9 months to 10 years. Median survival was 8 months, with tumors involving lymph nodes or distant metastases associated with a markedly worse prognosis (median survival 7 months) than stage I disease (median survival 27 months). CONCLUSIONS: The prevalence of lung cancer in lung transplant recipients is low. Using accepted donor screening criteria, donor derived malignancy is exceptionally rare. While stage I disease is associated with improved survival in this cohort, survival is still not comparable to that of the general population, likely influenced by the need for aggressive immune suppression.

RESUMEN

Cannabis is the most commonly smoked illicit substance in the world. It can be smoked alone in plant form (marijuana) but it is mainly smoked mixed with tobacco. The combined smoking of cannabis and tobacco is a common-place phenomenon in our society. However, its use is responsible for severe pulmonary consequences. The specific impact of smoking cannabis is difficult to assess precisely and to distinguish from the effect of tobacco. Marijuana smoke contains polycyclic aromatic hydrocarbons and carcinogens at higher concentration than tobacco smoke. Cellular, tissue, animal and human studies, and also epidemiological studies, show that marijuana smoke is a risk factor for lung cancer. Cannabis exposure doubles the risk of developing lung cancer. This should encourage clinicians to identify cannabis use and to offer patients support in quitting.

RESUMEN

SETTING: Sub-Saharan Africa carries a high burden of lung cancer, with limited access to specialised health care. OBJECTIVE: To investigate the diagnostic value of sputum cytology and its potential in reducing the need for invasive diagnostic procedures in a high-risk population. DESIGN: We collected spontaneously expectorated sputum from 108 patients referred for a diagnostic procedure for suspected lung cancer between June 2010 and June 2012, and examined the diagnostic yield of sputum cytology for malignant cells as well as factors predicting a positive result. RESULTS: Bronchial carcinoma was diagnosed in 90 patients (83.3%), of whom 35 (38.9%) had sputum cytology positive for malignant cells with 100% diagnostic accuracy. Positive sputum cytology was significantly associated with endobronchial tumour and obstruction seen during bronchoscopy (OR 4.69 and OR 8.89, respectively), and with a histology of squamous cell carcinoma (OR 1.9). All but one patient with positive sputum were inoperable (97.1%), and we estimated that up to a third of all invasive procedures could be avoided if sputum cytology was used for triage. CONCLUSION: Sputum cytology had a high yield and accuracy in this high-risk group. Its routine use in selected patients is likely to result in reduced costs and less patient risk and discomfort.

RESUMEN

BACKGROUND: Aspergillus antigens such as galactomannan antigen, a cell wall polysaccharide, can be detected in patient's serum or bronchoalveolar lavage. To study the prevalence of Aspergillus infection in patients with bronchogenic carcinoma, we measured galactomannan antigen in serum and bronchoalveolar lavage samples of patients with bronchogenic carcinoma. METHODS: The study was conducted on 45 bronchogenic carcinoma patients. The diagnosis of lung cancer was confirmed by bronchoscopy, histopathological and radiological examinations. Bronchoalveolar lavage fluid collected from each patient by fiberoptic bronchoscopy was subjected to direct microscopy and culture on Sabouraud's dextrose agar and Czapek-Dox agar, and Aspergillus galactomannan antigen was measured in serum and bronchoalveolar lavage samples. RESULTS: The majority of patients were male (93.3%) in the age group 51-60 years, 88.9% were addicted to gutka chewing, and 82.1% were addicted to smoking. Most patients complained of cough (73%) and shortness of breath (51.1%). Squamous cell carcinoma (64.4%) was the most common malignancy, followed by adenocarcinoma (13.3%). On culture of bronchoalveolar lavage samples, 35.5% showed growth of Aspergillus spp. (Aspergillus fumigatus in 17.8%, Aspergillus flavus in 13.3%, and Aspergillus niger in 4.4%). Galactomannan antigen was detected in 58.3% of bronchoalveolar lavage samples and 47.2% of serum samples. CONCLUSIONS: There is a high prevalence of aspergillosis in patients with lung carcinoma, especially among smokers and gutka chewers.

RESUMEN

PURPOSE: Patients who continue to smoke after the diagnosis of bronchogenic carcinoma (BC) experience increased rates of morbidity and mortality. Evidence suggests that smokers are more likely to quit if they are counseled by their physicians. However, there may be a prevailing belief among physicians that treating tobacco dependence is futile in this population. The purpose of this study was to investigate whether physicians addressed smoking cessation with patients who were diagnosed with BC. METHODS: A retrospective medical record review of patients who were diagnosed with BC between 2008 and 2010 was conducted at a community medical center using the hospital cancer registry. Demographic information including age, race, sex, stage, and smoking status at the time of diagnosis was collected. Evidence of tobacco cessation counseling was sought through billing codes, physician notes, and orders surrounding the time of diagnosis. RESULTS: A total of 948 patients were diagnosed with lung cancer between 2008 and 2010; 438 were current smokers at diagnosis, and only 36% were counseled on smoking cessation. On average, each patient encountered three different physicians in both the inpatient and outpatient settings. Of note, patients with stage I disease were 1.7× more likely to be counseled than those with stage IV disease (P=.017). CONCLUSION: Despite evidence that smoking cessation is beneficial even after the diagnosis of BC, physicians are not counseling their patients sufficiently. With the implementation of quality improvement programs, we expect smoking cessation counseling for patients with BC will improve.

RESUMEN

INTRODUCTION: The increase in the number of cancer survivors, together with the improvement of their follow-up, lead to the frequent diagnosis of resectable non-small cell lung cancer (NSCLC) in patients with history of previous malignancy. We sought to analyse the outcomes of these patients. METHODS: Patients undergoing surgical resection for NSCLC between January 1980 and December 2009 were retrospectively reviewed. For each patient, the presence of previous malignancy was noted, and classified into five groups: oro-pharyngeal cancer, lung cancer, haematopoietic malignancy, other organ malignancy, and more than two cancers. RESULTS: The overall population included 5846 patients. Among them, 1243 (21%) had a history of previous malignancy, of whom 383 (31%) presented with synchronous cancer. Patients with history of previous malignancy were more often female, older, with more adenocarcinomas, more limited disease, less pneumonectomies, but higher postoperative morbidity and mortality. Overall survival was worse in patients with a history of previous malignancy than in patients without (median, 5 and 10 year: 33 months, 34.3%, 17.8% versus 47 months, 44.6%, 28.8%). CONCLUSION: A history of previous malignancy impacted significantly the prognosis of patients operated on for limited NSCLC. However, only surgical resection led to improved long-term survival at 5 years.
